: In Figs. 1 :and Quat :32 is shownthe trans mission r case, 1 thecontained transmission being 'more fully: disclosed in Figs. 3,4T2t1ld5. At 533 a is shown a cone clutch for engaging the flywheel 3.4 "oftherengine 21 for power transmission. At 35 isrseen a shaft housed inbearingsififi, 37 inithe transmission case 32,St'l'd3 shaft 35 beinmprovided with a key- WayB 8 on which is slidablymonnted the: gear 39whic'h has; a grooved 11 huh I l-0s adapted :to engage anarma1,--whi@harm byxfurthentlescribed means i controls "the position ":ofthe gear on the whey Wayne-weed shaft 9 35. Thewgear fitl is alsoprhvidedvtitha block cluttch 42. Rotatablyr and slidably mounted onesecond shaft 43' housedat 44 and 45 in thecase 32 is awsleevewtdintermediate and integral with gear 47' and gent 8. At 49 is seen a 7gear: rotatablyi mounted en shaft 35 and attached to gear ldisrafismaller gear 50. Meunte'dtbetween the two driving 'shaftsfifil and:52- is the: differential 53 and attached to the differential .53 is thelarge? driving" gear tit-which is: in-mesh with gear 50. lira-Fig. 5,gear 39 stands in nentrali and t gear 748 is in mesh With; gear 49.Movingthewarm 41 to the: right slides: the gear? 39 in mesh-With 47,this being shift forlowtgear drive. the a transmission into highwgear 1the: arm 41 is: moved to r the: left, the blocks 42 o1r39-engaging?similar blocks 55 integral with gear or reverse vgeardrive, the i g'ear39 standsiin neutral as inlFigr 5; fan arm 5'6 engages a; grooved hubr57 said i arm "56 to the left by means later de scribed will plate 62bolted to frame bar 10. The selectivelever 63 is of l..-shape and ispivotally attached at 64to across bar of frame 10. The lever 63 has twonotches 65 and 66 formed therein :and at its lower end at 67 on gear 47;moving as ltlltlli bars of the frame 10. If

is a rod connecting to a crank 68 rigidly attached to a rod 69. This rod69 is housed in front and rear bearings as at in cross the lever 58 bedrawn back into notch 65 of lever 63 and then the lever 58 be moved toright or left, the lever 63 will pivot on 64 whereby the rod 67 andcrank 68 will cause rotary motion to the rod 69. This rotary motion of69 accomplishes the desired gear shift as will now be described.v The.shaft 71 slidably housed at 72; 73 in the case 32 is rigidly attached t0the shifting arm 41 engaging the hub 40 of gear 39, an end block 74forms a T head on shaft 71 and farther back on said shaft 71 at 75 is asecond block. The rod 69 passes through and is swiveled to a bar 76 at77, the upperend of bar 76 is adapted to play betweenthe blocks 74 and75 on shaft 71 whereby rotary movement of the rod 69 previouslyexplained will cause the bar 76 to move the block 75 to the left of theblock 74 .to the right as indicated by the dotted position seen in Fig.5, thereby shifting the gear'39 on the keyway 38 in the directiondesired to accomplish desired gear shift for forward speeds. Forreversegear, the lever 58 is drawn to the right and back into notch 66 of lever63 where'58 comes into contact with a rod 78 which has a right angle.bend

projecting through 63 into 66 as shown at 79. The rod 78 is adapted toslide in and pivot in a bearing at 80 on the frame 10. To the end of rod7 8' at 81 is pivotally attached the rod 82 which is pivotally attachedto the lower end of bar 76 at 83.

Thus by drawing the shift lever 58 backward into 66,1it will force rod78 to pivot at 80 causing 82 to travel forward causing bar 76 to movebackward as shown to the dotted positi'on'76 Figs. 8 and 9 between thetwo blocks 84 and 85 on the shaft 86 which carries the attached shiftingarm 56. Movement of the lever 58 to the left in 66 will now cause thebar 76 to drive the block 85 to the left to cause the arm 56 to move thegear 47 in mesh with 39 as previously described for reverse gearoperation.

It being desired to hold a tension on the bar 7 6. I have provided aspring 87 properly mounted on parts on the frame 10 as seen in Figs. 8and 9. At'88 is an L-shaped crank, hinged at 89 to the frame 10 andagainst which'the spring 87 bears. Integral with '88 is a right angleoffset bar 90 which passes through an eye 91 in bar 76 whereby thespring 87 exerts tension on 76 whether standing between the'blocks 74and 75 or as at 7 6 and shifted to theleft for reverse gear, when thepin Y attached to frame bar 10 resists such spring action.

Referring to Figs. 3, 4 and 5 and 10, the cone vclutch 33 has its hub 92housed on the engine shaft 93. The hub 92 is provided with teeth 94.Bigidly attached to the shaft 35 is a hub 95 provided with teeth 96meshing with teeth 94 on hub 92 of 33. Attached to the hub 95 are threearms 97 carrying springs 98, spring guides 99 and tension screws 100.Slidably mounted upon the shaft 35 is a grooved collar 101 having threepins 102 rigidly connecting to the hub 92 of the clutch 33. Whentransmission is to be thrown into gear, a rod 103 connected with theshifting lever 58 operates torelease the clutch 33. This rod isconnected to an L-shaped crank 104 hinged at 105 to the frame. Rearwardmovement of 58 thus forces the inner end of crank 104 engaging thecollar 101 to draw said collar to the right, compressing the springs 98and releasing the clutch 33, the teeth 94 sliding upon teeth 96 as willbe seen. -When desired shift of lever 63 has been accom lished, thesprings 98 then act to engage the clutch 33 with the flywheel 34 and thelever 58 drops into a notch as at 106 or 107 of the plate 62. It will beseen that by this arrangement it is impossible to shift gears withoutdisengaging the clutch thus liability of stripped gears is obviated.

At 108 on shaft 35 is seen a pulley wheel. Gears 109 attached to thedriving shafts 51 and 52 mesh with gearing 110 on the rear drivingwheels 13 whereby the tractor is propelled.

Such modifications may be employed as lie within the scope of theappended claims.

Having fully described my invention what I now claim as new and desireto secure by Letters Patent is:

1. In a tractor, the combination of clutch mechanism including clutchmembers, spring means tending normally to maintain the clutch members inengagement, and means to disengage the clutch members; a transmissionmechanism including shiftable gears, rods associated with some of saidgears for shifting them, and a pair of blocks carried by each of saidrods; and shifting mechanism for the clutch mechanism and thetransmission mechanism including a shifting lever oscillatable in twoplanes, means connecting the shifting lever and the clutch disengagingmeans, an oscillatably mounted rod, means for oscillating the rodincluding amember having two shift lever engaging notches, a selectivelever pivoted to and oscillatable with said oscillating rod and havingits upper end adapted to engage between blocks of either of said gearshift rods, means tending to normally maintain the upper end of saidselective lever in engagement between the blocks of one of said rods,and means associated with the lower end of the selective lever andhaving a portion projecting within one of the notches whereby when theshift lever is engaged in said notch the means is operated to move theselective lever into engagement between the blocks of 1 insane? theother gear shift rod, movement of the shift lever in one plane to engagethe notches serving through the disengaging means to disengage theclutch and movement in the other plane after engagement with anotchserving to move a shift rod.

2. In a tractor, the combination of clutch mechanism; gearing; andshifting means for the clutch mechanism and gearing; said shifting meansincluding a shift lever, disengaging means for the clutch connected withsaid lever, gear shifting means adapted to be engaged by the shift leverafter the clutch is disengaged, including a plurality of gear shiftrods, a member engageahle with either of said rods, means to move themem- Gopies of this patent may be obtained for five cents each, byaddressing the Washington, D.
